Fig. 3 is upon and turned by shaft D. The forward 45 a vertical section of the machine, taken at the end of the reciprocating bar 19 is pivoted to 5 dotted line 3 3 of Fig. 2 and looking at that one end of an oscillating bar b, whose other side of the section which faces towardthe end is pivoted to the lower portion of the upupper end of the sheet in which Fig. 2 is conright A or other suitable support. The functained, and omitting from view the mechantion of the oscillating bar Z7 is to uphold the 50 ism pertaining directly to the feeding of the adjacent end of the reciprocating bar b and its revolving roll I). The revolution of cam 1) causes the bar b and the plunger b to properly reciprocate.

A shaft E is journaled in supports, as e 6 Between these latter and on the shaft E are the two circular supports or disks e 6 which hold the soap-dies O in position. "Thenum ber of such soap-dies C may be varied, the preferred number here shown being four, arranged at equal distances apart around the shaft E. The as a is provided with a series of stops e arranged to engage consecutively a spring-finger e (whose fixed end is connected to the floor A or equivalent support) at the time that an empty soap-die comes opposite to the feed-plunger b. The soap-dies O and their supporting-disks e e rotate in the direction of the arrows marked on the disk 6 The mechanism for stopping the empty soap-die when opposite to the feed-plunger b and for holding it there while the plunger is feeding a cake of soap in the die and for then releasing it and for rotating the disks 6 e. and the soap-dies is as follows: In the outer side of the disk e are four curved grooves, as 6 each deepening in the direction in which the disk 6 rotates. On the shaft E is pivoted a lever (2 The upper end of this lever carries a stud e*, which works successively in said grooves c. This stud is pressed forward against the disk a by means of a spring e contained in the head 6 of the lever 6 The lower end of this lever e is pivotally connected to one end of a connecting-rod e and is rcciprocatedthereby. As the lever e is moved forward-that is, toward the guideway-B- the stud ascends the inclined bottom ofone of the curved grooves, and the stud e is pressed back into the head e of the lever e until the stud e comes opposite the deepest part of the succeeding groove e at which time it will there enter said groove, as shown in As soon as the feed-plunger b has inserted a cake of soap in the die 0 adjacent thereto the lever c is reciprocated from right to left, and the stud e impinges against the abutment e of the groove e in which it (the stud) is resting, and moves the disks-e e and the dies 0 forward in the direction of the arrows Z Z one-quarter of an entire revolutionviz., until the empty soap-die next following the one filled is brought opposite to the feed-plunger b". This die being filled with a soap cake and the lever e reciprocated, the stud e acting against the abutmentof thesucceedin g groove, carries the disk around another quarter of a circle and presents another empty die to the feed-plunger to be filled. In this manner the empty soap-dies are successively presented to be filled.

When an empty soap-die is brought opposite the feed-plunger b, it is firmly held in position by the following means: A stop e is fixedto an elastic spring-plate e fixed to the bed A or frame of the machine. On the peperiphery of one of the disks,

riphery of disk e are four studs e one for each soap-dieviz., one accompanying and adjacent to a soap-die. As the disks a e are rotated, one of these studs (2 impinges against the stop 6 when the adjacent empty soap-die is directly opposite plunger b and in position to be filled. The stop .9 thus holds the disk secure from forward rotation,while the springfinger e fitting under and against stop'e prevents the return or back movement of the disks and soap-dies. Thus the dies 0 are firmly held in a fixed position while the feed plunger is filling a die with acake of soap.

The rod 6 is reciprocated by a crank movement. As shown herein, the rear end of this rod e is pivoted to a crank pin or wrist e", fixed in the side of cam b and operated by shaft D. The same crank-pin operates to re tract the stop e? and thus disengages it from the stud e with which it hasbeenin contact. For this purpose thefree end of this pin is provided with a friction-roller e which as the crank-pin reciprocates comes into contact with the bearing e of the stop e and pushes the stop (2 back out of contact with the stud e of the disk e. This disengagement of the stop e from stud e takes place immediately before the reciprocation of the rod e and lever e and causes the disks and soap-dies to be advanced one-quarter of a circle. While one soap-die is held in.position for being filled another with an unstamped cake of soap is under the soap-stamp, and while the first-named die is receiving its empty cake of soap the soap in the laternamed die is being stamped. Thus the mechanism which holds the disks stationary for an empty die to be filledat the same time holds the die under the stamp stationary while the soap in the latter is being filled. The soap-stamp O is of the usualform, and-is operated by a shaft 0 sliding through a guide 0 The stamp is elevated by the following means, viz: A vertical square shaft 0 slides in a vertical guideway 0 This shaft 0 is provided with a lower arm-C and an upper arm 0 whereby it is rigidly connected to the stamp-shaft C The arm 0 passes through and slides in close-fitting slots, forming the guideway 0 One of these slots is shown in Fig. 1 and the other is opposite thereto on the I other side of the guideway. Thus the arm 0 and the stamp C alwaystravel in fixed vertical planes, and the stamp always properly strikes the cake of soap in the die directly beneath it and entering the die stamps the soap cake. The shaft 0 and the stamp O are elevated by a cam 0 provided with an abutment 0 which strikes against a shoulder 0 rigidly fixed to the shaft 0 The cam O is fixed on shaft D. After the shoulder C has mounted onto the abutment C it remains on the higher peripheral surface of the abutment until it comes to an abrupt end O 'of said abutment, when it is free to fall and does rapidly deseend until it impinges upon the lower peripheral surface of the cam. The shaft '0 is the disks 6 6 is raised to the position shown in said Fig. 1

raised up fromthe soap to the position shown inFig. 1, where it is above the top of the die. The latter is thereby free to be rotated with The means whereby the stamp consists of the spring 0 fixed on stationary seat 0 of the frame and elastically pressing against the stud O fixed to the shaft 0. The further elevation of the stamp is effected by the cam 0 as hereinbefore described.

A device is present' for ejecting the soap cake from the die after said cake has been stamped, and consists ofa stationary curved ejecting-guide 0 Each die has a false bottom, which is capable of freely moving in the die toward the mouth of the latter or toward the bottom of the latter. This false bottom (J may be termed an ejector. Itis provided with a shank 0 which passes through the real bottom of the die, and is provided with the pin 0 to prevent the shank from sliding so far through the die-bottom as that the false bottom shall leave the die. As the dies are rotated, the free end of the shank C of the die just leaving the soap-stamp impinges against the ejecting-guide C and as the disks are rotated the ejecting-guide forces shank O outward and the ejector is thereby moved outward, through the die to the mouth of the latter, and the stamped cake of soap therein is ejected and received on a proper table or in a suitable receptacle.

For the proper cleansing of the false bottom of the die a swab T is provided, attached to the bar T. As the dies move forward, their false bottoms are successively cleaned against the swab.

tical guide 6 and is worked by a crank-arm S in turn operated by a rod S at one end pivoted to crank -arm S and at the other end pivoted to a connection of the bar 19 Thus the reciprocation of the bar 12 operates the rod S in turn operating rock-arm or crank S which latter operates the stop S. (See Figs. 2 and 7.) The loose cakes of soap within the guide B are thereby held within the guide until an empty die has come opposite the plunger b As the plunger advances and presses the lowest cake in the guide forward into the adjacent die, the stop Sis lifted out of the way and the cake is free to pass out of the guide into the die. As the plunger, after inserting a cake into the empty die, retracts, the stop descends and keeps the remaing cakes of soap in the guide until the plunger advances and fills the next empty die.

A receptacle, as V, is filled with a suitable liquid for the swabs, to iise in cleaning the false bottom of the die and the bottom of the stamp. This liquid is conveyed to swab T by a conduit T and to swab S by a conduit T2. The flow of liquid through these conduits is regulated by faucets, as V. The swab S cleans the bottom of the stamp O. This swab is fastened on the crank-wrist of the crank S operated by the rod S )ivoted to the uprights A A of the frame, and provided with the crank S ,at its free end pivotally connected with the rod S pivotally connected to the oscillating end of bar-S at its lower end pivoted at S to the frame and operated by abar S at one end fixed to it. The bar S has at its other end a roller-stud S fitting into a cam-groove S in the side of the cam S fixed on shaft D. After the stamp has been elevated to the top of its vertical stroke, and before it is dropped, the swab S passes over its face, washing it and removing therefrom any particles of soap that may be adhering thereto.

The mode in which my invention operates as an entirety is as follows: The cakes of soap to be stamped are fed to the feed-guideway B. The lower one of these cakes of soap is inserted by the plunger 12 into the adjacent soap-die O. A partial revolution of the crankshaft carries this die under the stamp, and a fresh empty die comes opposite the plunger. WVhile the plunger is feeding another cake to the empty die the stamp is raised, swabbed, and dropped, and stamps the cake in the die immediately beneath it. A second partial (quarter) revolution of shaft D ejects the stamped cake from its die and presents an empty die to be filled in front of the plunger and a filled die under the stamp. Thus the operations of fillinga die with a soap cake and stamping the cake in the preceding die and ejecting the stamped cake from adie preceding the last are continued until all of the soap to be stamped has passed through the machine.

It will be observed that all of the beforenamed mechanical movements are made by one shaft D. This one shaft may be rotated in any suitable manner. Band-pulleys (the one D being tight and the other D being loose) are here shown as one means for rotating said shaft D.

While the various features of my invention are preferably employed together, one or more of the said features may be used without the remainder, and in so far as applicable one or more of the said features may be used in connection with soap-stamping machines of a description other than the one herein specifically described.
